The frame of 1 * 1 * 0.9m and 800kg shall be placed on the hydraulic lifting device by the forklift, lifted, immersed in the water pool, turned over and dumped, and then the empty frame shall be transported out. This whole process only needs 2 minutes to ensure the processing capacity of each line of 10 tons / hour. The device greatly reduces labor input.
1. Bubble Washing Tank
The pool is 2 * 2m long and 2 * 2m wide. The bottom is funnel-shaped, with water pressure boosting on the side and adjustable water pressure.

The water depth of the chemical bubble tank is 1.5m and the length is 2.5m. Make sure the sweet potatoes can be sterilized in water for 2 minutes.The angle of the brush elevator raised from the pool is close to the horizontal. To prevent the chemical coating from being brushed off due to the large angle, then the horizontal part is a natural air drying area of 2m.
